seem to remove it from that genus. In the great height of the 

 basals the species agrees with members of the genus Rhisocrinus, 

 but that genus is described as having a thin, disk-like proximal 

 stem joint, while the New Jersey species apparently has an ex- 

 ceedingly high one in which no transverse divisions can be 

 detected. There seems to be no reason, however, why some lati- 

 tude may not be allowed in this character. The genus Rhizo- 

 crinus has not heretofore been recognized earlier than the Eocene, 

 but there is no reason why it should not also occur in the higher 

 Cretaceous beds. 



The species is possibly allied to Boiirgueticrinus alabamensis 

 De Loriol, a species which Carpenter thinks should be referred 

 to the genus Rhizocrinus? The New Jersey species differs from 

 that species in its much more elongate and more slender form.
